We present an anomaly not previously described in the literature where the FDP to the ring finger was found to originate from the FPL tendon, causing tight flexion contracture of both due to underlying muscle spasticity. An year-old boy with Leigh syndrome was under the care of our plastic surgery unit for flexion contractures of his upper limbs. Of note, pre-operatively he had a very tight FPL and wrist flexors but also incidentally a severe flexion deformity of his ring little and fingers which resembled a claw hand.
During surgical exploration and release of the muscles, an anomalous fusiform muscle was found originating from the tendon of the FPL, heading to the ring finger and flexing the distal interphalangeal joint. The accessory muscle was divided and improved the flexion contracture. Anatomically distinct from the anomalous tendon slips described by Linburg and Comstock, this accessory muscle actually originated from the FPL and inserted in the ring finger.
While most anomalous muscles are asymptomatic, ours was causing symptoms particularly due to underlying muscle spasticity. The other clinical relevance of this is that the ring finger FDP usually supplied by the ulnar nerve was in this instance supplied by the median nerve. We present the case of a 28 year old male mechanic who presented with a painful swelling over his right thenar eminence following a road traffic accident.
Shortly afterwards he noticed a swelling in his right palm over the first web space which increased in size with finger flexion. His grip strength was compromised and had reduced abduction of his index finger.
Ultrasound and MRI scans were inconclusive. No intrinsic muscle rupture was detected and no mass lesion was detected. Hypertrophy of the index intrinsic muscles was suggested. The swelling increased in size and his overall hand function decreased, so surgical exploration was planned. At operation, the FDP tendon to the index finger and the intrinsic muscles were intact and of normal appearance.
However, an accessory muscle was seen attached to the index finger FDS tendon in zone 3. A tendon ran proximally from this accessory muscle belly into the forearm. The accessory muscle was excised from the FDS tendon and the accessory tendon was sutured end to side on the existing FDS tendon. Postoperatively, the patient made a full recovery with reduced pain and significantly improved hand function. Anomalous and accessory muscles in the palm are anatomical curiosities until they become symptomatic.
Accessory FDS muscles presenting in the palm are rare and only a few cases have been reported in the literature since they were first described in by Vichare. However, significant functional problems have been reported in conjunction with these anatomical variations, including pain, compression neuropathy, digital triggering and stiffness.
Because of their rarity, their diagnosis is often delayed or initially missed. The authors show clear anatomical photographs of this accessory muscle along with an algorithm for investigating suspected anatomical variations.
Two major lunate types have been proposed on the basis of the absence Type I or presence Type II of medial facets. The first purpose of this study was to examine the reliability and reproducibility of the two methods of determining the lunate type: The second purpose was to investigate the compatibility of the radiographic classification of lunate types with MR arthrography MRA findings.
Plain radiographs of a total of wrists were reviewed by three observers. The Cohen kappa and Fleiss kappa statistics were used for estimating the intra- and inter-observer reliabilities. The compatibility of the lunate types with the MRA findings, as assessed by each observer, was investigated.
The overall intra-observer reliability was 0. The overall inter-observer agreement of the three raters was 0. The PA analysis and MRA findings for the detection of medial facets of the lunate were compatible in of the patients On the CTD analysis, 76 Both systems had moderate inter-observer and intra-observer reliabilities.
Although the Type II lunates on both radiographic analyses showed a good compatibility with the MRA findings, clinicians should consider undetected medial facets in Type I lunates on PA analysis. In the musculoskeletal system, structure dictates function and the development of pathology. Interpreting wrist structure is complicated not only by the existence of multiple joints and ligamentous structures but also by variability in bone shapes and anatomical patterns.
A previous study evaluated normal plain radiographs for lunate and capitate shape in the midcarpal joint. This study identified intracarpal measurements related to lunate and wrist type. Assuming that these disparate patterns will transfer forces differently, our purpose was to correlate the forces transferred to the distal radius and ulna with the morphological measurements in cadaver arms. Radiographs from a database of 49 cadaver wrists previously tested for force transfer between the radius and ulna were examined.
The percentage of the compressive force through the distal ulna and radius was determined by mounting load cells to the distal radius and ulna while Each wrist was tested in neutral flexion-extension and radioulnar deviation. There were 35 lunates type 1 with a mean ulnar force of This has been published in a previous study.
This may support that a type 2 wrist transfers forces differently through the wrist. Nerve section is often present in patients with hand trauma. Section of the digital collateral nerves needs appropriate repair to regain sensibility to support physiological local forces to allow early motion in case of concomitant flexor tendon section. This study characterizes the mechanical behavior of digital collateral nerve to stablish their healthy mechanical properties.
Digital collateral nerves were preserved in sodium chloride 0. A correlation and independence test were applied to the values to explore the relationships between groups each finger: The stress- strain curve and young modulus were shown. The mean values found for the digital collateral nerves were: The scanty number of samples did not allow to stablish a significant difference between fingers, neither was possible to stablish a correlation between density and Young Modulus. A linear regression model for the scatter plot of nerve specific modulus and specific stress showed a tendency to direct correlation between these variables.
Digital collateral nerves biomechanics are the first step toward a development of a better nerve repair. Data acquired during the experiment can be used to improve simulations of nerves during training and surgical planning. Further studies should correlate the ex vivo data with non-invasive techniques as in vivo elastography. Allen Buckner Kanavel was an American surgeon, best remembered for describing the cardinal signs of suppurative flexor tenosynovitis.
With international concern over antibiotic resistance, it is timely to reconsider the role of surgery preceding the availability of antibiotic medication. Therefore, better understanding of the way infections in the hands can spread is of paramount importance in managing our patients. To determine the communications between each fascial space, Kanavel injected a solution of radio-opaque dye mixed with diluted Plaster of Paris from different entry points, such as the tendon sheaths, wrists, and deep palmar spaces.
The solution was injected at different pressures into a formalin-hardened hand specimen to observe where infections would spread when the spaces ruptured.
He then took X-rays then the novel Roentgen rays of the injected hand specimens and performed cross-sections to better delineate these spaces. These spaces described will be illustrated by MRI images of current cases. He described two main deep spaces of the hand: The middle palmar space was bounded by the third metacarpal to the radial border of the fifth metacarpal bone, with a thin fibrous septum separating it from the tendons that lie anteriorly. The thenar space was said to be bounded by the adductor transversus posterolaterally, and the flexor tendons anteriorly.
The septa between these two spaces are thick, firm, and essential in preventing spread of infections. We were initially drawn to his initial study as we noticed it was rare to come across infections of the hand that conformed to his boundaries of the deep fascial spaces in actual clinical practice. Similarly, several later papers had varying descriptions of the boundaries of the deep spaces.
For example, Grodinsky performed dissections and injections on 92 hands describing many other spaces with indeterminate septa within. One possibility for this discrepancy was that cadaveric studies were unable to replicate the erosive and inflammatory processes of an active infection. Another possibility would be inaccurate interpretation of the dissections, as the spaces were mainly illustrated through hand-drawn images by different artists.
Modern imaging should be performed to delineate relevant spaces that are encountered during infections. The donor vein for constructing AV-loop graft was small saphenous vein graft.
Currently there is no anatomical study about size, length and number of branching of small saphenous vein. To study anatomy of small saphenous vein, size and number of its branches and its valves as a vascular graft option for use in AV-loop graft in FFMT reconstruction in BPI with concomitant subclavian artery injury. The anatomy of the small saphenous vein was studied in 30 legs of fresh and soft cadavers.
There were 15 females and 15 males with mean age The total length of small saphenous vein was measured over the complete length of the leg. Recorded location, size and number of branches. We used retrograde saline injection to locate valves direction. Statistical analysis was performed by SPSS The average length of small saphenous vein taken from distal edge of lateral malleolus to the point where small saphenous vein connect to popliteal vein was The average diameter of proximal and distal end was 0.
The average frequency of branches was The average size of branches was 0. The distance from each branch to distal end ranging from 1. Valves of small saphenous vein allow bidirectional flow. Knowledge on the anatomical variations and characteristics of the small saphenous vein can be helpful in clinical practice and surgical operations concerning patient with BPI patients who undergone AV-loop graft in FFMT. Universitat de Barcelona, Barcelona, Spain Objetives: This study aimed to describe the role of the Pronator Quadratus PQ muscle and the Anterior Interosseous Artery AIA in the vascularity of the distal radius and its relationship with the union in distal radius fractures.
Sixteen adult hands from fresh cadavers were dissected. There were 8 male and 8 female with a mean age 72 years range, years. Dissections were performed using magnifying loupes and vascular anatomy was studied. Hands were processed using soft tissue digestion and bone clearing using Spalteholz technique.
The PQ muscle originates from the ulna by a strong aponeurosis. The muscle is attached to the flexor surface of the distal radius and also on its medial triangular area, proximal to the sigmoid fossa. The distal border of the muscle covered the distal radioulnar joint and is on average 14 mm mm from the lower articulating surface of the radius.
The AIA is a terminal branch of the common interosseous artery IA , but it occasionally arises from the ulnar artery. The AIA is accompanied by its venae comitantes and the anterior interosseous nerve, all of which lie on the flexor surface of the interosseous membrane, deep to the PQ muscle. The artery, along its course gives a series of perforating branches at intervals of 15 mm.
The distal radius was supplied by three main vascular systems: The palmar epiphyseal vessels branched from the radial artery, palmar carpal arch and anterior branch of the AIA.
Every specimen studied had one o more palmar metaphyseal arch that coursed through the PQ. In the metaphyseal area we found numerous periosteal branches originating deep in the PQ and the AIA. These branches provided the main supply to the distal radius. Vessels perforated the bone and formed an anastomotic network. In the diaphyseal area only the nutrient vessel provided intraosseous vascularity in the distal radius.
Numerous metaphyseal branches arise from the deep PQ muscle and the AIA course towards the distal radius. These branches allow the union of the distal radius fractures and they make that the nonunion be an uncommon complication. The main vascular contribution takes place by deep fibers of the PQ, so that the superficial fibers can be surgically approached for a plate with a minimum risk of injury to the vascularity. Brachial plexus 1 abstracts.
There remains a shortage of literature showing what might be achieved with delayed secondary neurotisation following severe extremity trauma. This case shows what may be achieved if challenging trauma is managed within an effective protocol and timely access to expertise. Case Report A year old male sustained a subtotal amputation of his left arm requiring vein graft revascularisation. Other injuries included a divided axillary artery, fractured clavicle and ruptured musculocutaneous nerve with intact posterior cord of the brachial plexus, median nerve and ulnar nerve.
Total ischaemia time was less than 4 hours. The patient made a good recovery and was discharged two weeks later. Three months post-injury the patient had full hand function and sensation and elbow extension, although he scored M1 for elbow flexion, M3 for trapezius function and M0 for shoulder abduction.
He underwent a nerve transfer of a median nerve motor fascicle to the brachialis muscle and received physiotherapy and electrical neuromuscular stimulation post-operatively. We carried out a nerve transfer of the posterior motor branch of triceps to axillary nerve. He has regained almost full shoulder abduction and returned to his usual pre-morbid employment.
Discussion The high volume of severe trauma at our centre has enabled us to develop an effective trauma system which successfully manages candidates for limb salvage. However, when this patient presented there had been little published utilising delayed nerve transfer following mutilating upper limb injuries.
As a result, we had to establish our own practice. We consider three months a reasonable time for secondary procedures as the skin should be supple and swelling-free.
For proximal upper limb injuries the restoration of elbow function should take precedence, followed by shoulder stability and active abduction and external rotation.
However, when we operated on this patient, the tissue scarring had made the nerve branch to biceps unavailable. Therefore, we chose to coapt a fascicle of the median nerve to the brachialis muscle branch within unscarred tissue. In this patient, the outcome resulting from brachialis reinnervation alone was excellent.
On returning for review 12 months the patient still needed improvement in shoulder function. As we could not use the spinal accessory nerve transfer to suprascapular nerve, we utilised the nerve branch to triceps to reconstruct the axillary nerve.
Physiotherapy and electrostimulation was given post-operatively and after 10 years the patient has regained almost full arm function. Conclusion This case is the first documented case showing an excellent functional outcome in a revascularised limb following nerve transfer at 12 months. We stress the importance of senior expertise and a clearly defined trauma protocol which minimises ischaemia time.
Mutilating upper limb injuries present a challenge, but modern neurotisation techniques, even if delayed, can result in success. At the first visit on the six day after onset, the X - ray was normal.
On the same day, MRI findings was osteomyelitis in the middle phalanx. However, the serum inflammatory response was negative.
Serum rheumatic response was also negative, but antinuclear antibody was positive at times. On the 12th day after onset of disease, the vicinity of the epiphyseal line of the middle phalanx became erosive.
At this point, from literature search and pediatric consultation, we got a diagnosis of Microgeodic disease. The antibiotic was discontinued. Pain was relieved 2. At 4 weeks after onset, the middle phalanx fractured and fixed with the splint.
Bone fusion was somewhat late. There was no deformation healing, but the epiphyseal line of middle phalanx and distal phalanx closed. At 7 months after onset, the difference in bone length between bilateral middle phalanges was 2 mm. The finger healed without dysfunction. Redness and swelling of fingers and toes like frostbite. It is accompanied by mild pain and itching.
Predilection age is elementary school age 6 - 12 years old. It is mainly in the middle phalanx. A bone resorption image is recognized in the X-ray image. The cause is unknown, it is thought to be a transient bone circulation disorder.
Prognosis is usually good, it will heal spontaneously in about 6 months. In this case, owing to attaching a diagnosis at a relatively early stage, appropriate treatment could be done.
Microgeodic disease was reported 24 papers in PubMed. Since the arterial arch of the hand is predominant on the ulnar side, it seems that this disease is many in the index finger. Oberg-Manske-Tonkin [OMT]-classification , but none of these describe involvement proximal from the wrist other than radio-ulnar synostosis.
One case of longitudinal cleavage of the upper extremity has been described in the literature. Materials and methods An otherwise healthy 8-month-old infant presented with congenital split right forearm. Results Starting from the elbow joint, the forearm is divided into a superior radial forearm with a thumb and an index finger and an inferior ulnar forearm with two fingers.
X-rays showed a radius and two metacarpals in the radial forearm and a hypoplastic ulna and a single metacarpal supporting two digits in the shorter ulnar forearm. The elbow joint of the radial part had an active and passive extension lag of 60 and 50 degrees, respectively, and an active and passive flexion of and degrees, respectively.
An ulnohumeral synostosis was present and the ulnar forearm showed no motion. Conclusions This is the first reported case of congenital forearm. A possible suggested ethiologic theory would be an error of limb bud specification in the 4th or 5th week of gestation. It has been suggested that the timing of an error in limb bud specification would determine the extent of duplication.
An early insult would lead to a more proximal division of the upper limb. We suggest that the case is a forearm cleavage - less severe than a total of upper extremity cleavage, but more severe as a conventional cleft hand.
We suggest that a new category — cleft forearm complex — be added to the OMT —classification. Xuyang Song, Alexandria L. Case, Rory Carrol, Joshua M. Emergency room transfers to a higher level of care are a vital component of modern healthcare, as optimal care of patients requires providing access to specialized personnel and facilities. However, literature has shown that upper extremity orthopaedic transfers to a higher level of care facility are frequently unnecessary. The purpose of this study was to assess the appropriateness of pediatric orthopedic transfers to a tertiary care center and the factors surrounding them.
All pediatric upper extremity orthopaedic transfers to our pediatric emergency department were evaluated over a four year period. A retrospective review was performed to assess the factors surrounding the transfer including patient demographics, time of transfer, day of transfer, insurance status, outcome of transfer, and diagnosis.
Three independent variables were utilized to assess the appropriateness of the transfer: The majority of pediatric upper extremity orthopaedic transfers are warranted as they require operative intervention, a closed reduction maneuver, or conscious sedation in the emergency department.
Pediatric upper extremity orthopaedic transfers do not seem to be influenced by the day of the week. Similar trends to those seen in adult upper extremity orthopaedic transfers are present regarding off hour presentations and high percentages of less desirable insurance statuses. Closed reduction and percutaneous pinning CRPP is traditionally performed following full surgical prep and draping, which can be inefficient and wasteful of materials.
The semi-sterile technique has been shown to have no difference in infection or complication rates when utilized for pediatric supracondylar humerus fractures. Therefore, the authors hypothesize the semi-sterile technique can be utilized for CRPP procedures of all pediatric upper extremity fractures. A retrospective review was conducted over a five-year period to identify all pediatric patients who underwent CRPP of an upper extremity fracture.
During this period, there was a gradual transition from utilizing the full preparation and drape technique to the semi-sterile technique. Factors assessed included demographics, fracture type and location, and length of pin fixation. Qualities of intraoperative care were assessed including average length of surgery, room set up time, and room cleaning time. Additionally, parameters of postoperative care were recorded including average length of follow-up and complication rates.
Simple statistics and unpaired t-tests were performed. Two hundred twenty four patient records were reviewed including in the semi-sterile group and 62 in the full preparation group. The average room setup time in the full preparation group was Furthermore, the average operating room cleaning time in the full preparation group was When assessing the setup time, procedure time, and clean up times together, the combined average times were Two complications occurred in the full preparation group including one pin tract infection and one physeal arrest.
The semi-sterile technique is a safe and cost effective alternative that should be used when performing CRPP of all pediatric upper extremity fractures. The full preparation technique increases operating room time and medical waste, and therefore should not be utilized when performing CRPP procedures.
Phalangeal neck fractures are a common orthopedic injury seen predominantly in the pediatric population. The indications for operative treatment are currently evolving. The purpose of this study was to determine the variation among orthopedic surgeons in their practice habits when treating phalangeal neck fractures. Twenty-five pediatric orthopedic surgeons reviewed sets of posteroanterior PA , oblique, and lateral finger radiographs of children less than 17 years of age.
In each clinical vignette, the age and gender of the patient was included. Surgeons were provided with 12 clinical vignettes and were queried if they would; 1 treat the fracture with immobilization or intervention? Additionally, surgeons were asked to complete a demographic questionnaire detailing their training and personal background.
The analysis was completed using a mixed effect model with the respondent as the random effect. This study found that for each advancing year of age, the surgeons are Fifth metacarpal neck fractures are common fractures affecting the pediatric population.
However, no true standardization exists regarding their treatment. The purpose of this study was to determine if variation exists amongst orthopedic surgeons in treating pediatric fifth metacarpal neck fractures and determine the factors regarding this variation. Twenty-five sets of images of pediatric fifth metacarpal neck fractures with posteroanterior PA , oblique, and lateral views were identified.
Fracture angulation measurements were made for the lateral and oblique views, with half of the images unmarked to assess the effect of marked angulation on treatment decision. The images, along with a brief demographic questionnaire, were evaluated by 25 orthopedic surgeons. Treatment of fifth metacarpal neck fractures in the pediatric population is not standardized. Worsening angulation above approximately 50 degrees and increasing age adolescence appear to be the most important factors when deciding to operate.
Improved treatment algorithms based on outcomes studies are needed to determine the optimal treatment. A total of 45 subjects and 21 patietns Male 13, Female 8, mean age The regular stretching exercises were performed in 31 subjects and the others got surgical correction. Flexor digitorum superficialis FDS tenotomy and volar plate release were done through surgical procedure. The two radiographic parameters were proposed for confirming the radiographic remodeling of camptodactyly called Beak triangle ratio and Beak angle.
Both parameters were measured using finger true lateral radiographs at initial visit. The same procedures for measurement on finger were done two years after intervention. The extent of proximal interphalangeal joint PIPJ contracture on passive functioning was evaluated to determine clinical outcomes from conservative and surgical intervention.
The mean Beak triangle ratio before intervention was mean 0. Methods We performed a retrospective review of 8 children with clinodactyly treated at our institution with a novel opening wedge osteotomy of the abnormal delta phalanx between and Preoperative and postoperative clinical angle, radiographic angle, digital range of motion, and pain were compared and complications were recorded.
Results 10 digits in 8 patients were included in the study. All had greater than 28 degrees of preoperative clinical angulation mean, 40 degrees. Mean age at time of surgery was 6 years; mean duration of follow-up was 24 months range, mo. All digits had significant improvement mean, 34 degrees in clinical and radiographic angles after surgery.
This improvement was maintained at final follow-up in all digits. One digit had a recurrent deformity at final follow-up and 3 digits developed stiffness at the interphalangeal joint. Conclusions Our novel opening wedge osteotomy is an effective treatment for angulation in children with severe clinodactyly although the risk of interphalangeal joint stiffness still exists. Radial club hand is a rare congenital anomaly of hand involving preaxial border of hand with incidence of 1 in to 1 in It is associated with deformities in forearm, arm and several other systemic anomalies.
Its severity ranges from mild hypoplasia of radius to complete absence of radius. In Indian context there were very less studies describing anomalies and this study aims at describing this anomaly. This study was a descriptive study aimed at describing Radial club hand anomalies and its association with other systemic anomalies during March to March collected from outpatient department of Balaji institute of surgery research and rehabilitation for the disabled hospital, Tirupathi, Andhra Pradesh, India.
We reported a total of 62 cases of radial club hand among which 24 were bilateral and 38 were unilateral. Male to female ratio was 2. Type 4 Bayne radial deficiencies were most common and type 5 Blauth hypoplastic thumb was most common finding.
All the finger deformities were more pronounced in index finger and were least seen in little finger. Other systemic anomalies recorded were absence of kidney 6. This study had recorded unilateral involvement of radial club hand to be more prevalent than bilateral. Association of systemic anomalies was less with bilateral radial club hand. Ten years ago in our department miniinvasive percutaneous osteotomy for malunited phalangeal fractures was developed by senior author.
Osteotomy in former fracture line is performed by larger injection needle. Presentation of the method and patient cohort is the aim of the study. The osteotomy can be performed only if 1. Under x-ray control the injection needle is inserted into callus which is step-by-step disrupted.
Instead of a fine needle a small elevator from 2 — 3 mm incision can be used. After releasing peripheral fragment is reduced and stabilized by percutaneous osteosynthesis from a separate entry. There are several possibilities of stabilization: From 17 patients with malunited fracture in all the osteotomy by injection needle was performed, in 3 additional use of a smooth elevator was necessary.
Supracondylar fractures were recorded in 10 children, unicondylar in 3, diaphyseal in 2 and intraarticular basal injuries in other 2 respectively. Functional and cosmetic effect was very good. A method of miniinvasive osteotomy of malunited phalangeal finger fractures is presented. Especially in delicate pediatric hand skeleton it can be a beneficial method bringing better results than classic orthopedic procedures.
Our above mentioned method is due to miniinvasive osteotomy procedure as well as stabilization maximally sparing soft tissues and can promise better cosmetic and functional outcome. Histological examination shows the picture of a benign osteochondroma. Most cases of this rare condition are reported in the lower limbs, and occurrence of upper limbs is relatively rare. However, when occurring in the hand, even when the lesion is small, the functional impairment, such as the axial deviation and the restriction of range of motion can become severer than other parts due to the intra-articular lesion.
We report six cases of osteochondroma at epiphysis DEH in the hand who underwent surgical treatment. Affected sites were three middle phalanx of middle finger, one proximal phalanx of thumb and ring finger and a third metacarpal bone. The average age at surgery was 9.
The average follow-up is We evaluated the site of occurrence, deformity, chief complaint, surgical procedure and outcome. RESULTS Sites of occurrence were the radial aspect of the proximal phalangeal epiphysis of one thumb, the radial aspect of the middle phalangeal epiphysis of one middle finger, the ulnar aspects of the middle phalangeal epiphysis of two middle finger, the ulnar aspects of the proximal phalangeal epiphysis of one ring finger and one proximal part of third metacarpal bone.
The angular deformities were localized at the proximal interphalangeal joint of a ring finger, and the distal interphalangeal joint of two middle fingers. At surgery, osteocartilaginous tissue was excised in all patients, and pathological examination showed an osteochondroma covered with cartilage in all cases. At follow-up, restricted range of motion in affected joint improved in all cases.
However angular deformity remains in two cases angulation: And recurrence was seen in the case of third metacarpal bone, so we performed resection surgery again.
If DEH occurs in hand, masses cause incongruity of the joint surface, angular deformity and restricted range of motion of the affected joint. It is necessary to perform the sufficient tumor resection after accurate diagnosis at early stage.
After excisional surgery, there are reports of arthritic changes and recurrence, so careful follow-up is necessary. Arthrogryposis is a descriptive term referring to multiple congenital contractures.
More than acquired and genetic diseases are labelled as arthrogryposis. Because of their rarity and complexity coordinated patient management is often lacking. Multidisciplinary clinics are the ideal setting to provide coordinated and comprehensive care to patients with special needs. These clinics are organized to bring together professionals from several disciplines, with the aim to provide patient centered, comprehensive clinical care, and reduce the burden of multiple medical appointments for the families.
A team approach to care has been shown to be beneficial in developing a treatment plan maximizing cognitive, physical, and social development for the child.
We report a 9 year experience of an interdisciplinary arthrogryposis clinic. Representatives from a patient support group are available. Patients are referred from a variety of specialties, eg foetal medicine, paediatric neurology, orthopaedics, genetics. Genetic diagnostic technologies have evolved, from single gene analysis, to gene panels for specific disease groups and exome or genome sequencing for more complex cases.
These assist accurate clinical evaluation and increase the chance of providing a precise genetic diagnosis and correct genetic counselling. Other diagnoses include conditions presenting with arthrogryposis as their main feature Freeman-Sheldon syndrome; Beals syndrome , cases where congenital contractures are described, but are not a typical sign of the condition DiGeorge syndrome; Ohdo syndrome or can be part of an unexpected diagnosis for a patient referred for contractures of extremities 16p An interdisciplinary approach reduces the number of appointments, provides patients with arthrogryposis with more specific diagnoses, coordinated orthotic and surgical management and informed physiotherapy.
In time, this helps build the expertise of the group, enabling it to provide more valuable services to the families. The relationships with the families are strengthened, as is adherence to treatment programmes. Families are pleased to attend a single multidisciplinary clinic rather than be followed up at a number of separate, individual clinics, and they are reassured by the combined expertise available.
Hypoplasia of the thumb occurs within a spectrum of hypoplasia along the radial side of the entire upper extremity It is a rare congenital deformity affecting 1 in , live births.
Congenital absence of the thumb, resulting in a loss of its prehensile ability, significantly affects hand function. To function correctly, the thumb must be positioned so that it can oppose the adjacent medial fingers and grasp objects securely from an antiposed abducted, slightly extended, and pronated position. We followed a groupe of patients in the period 29 children , 41 hands ,men 18x , women 11x 12 children have comorbidity radial club hand Most of them have had floating thumb problem o Results: The results, which were not entirely right, were evaluated and corrected o Conclusions:.
Pollicization is complicated procedure that may have some pitfalls. Additional surgery may improve the function of the thumb The work is documented by video showing some results. Partly due to disease rarity, ambiguity remains with respect to criteria for disease classification and optimal treatment strategy.
The purpose of this study was to evaluate the current literature concerning Madelung deformity to determine criteria used in clinical examination, surgical treatment options and operative outcomes. A comprehensive review of published literature from inception to was performed to identify all studies that described surgical intervention for Madelung deformity patients, adhering to the Meta-Analyses of Observational Studies in Epidemiology MOOSE guidelines.
Studies eligible for inclusion described a corrective surgery for Madelung deformity and reported post-operative outcomes. Studies were evaluated by level of evidence and a novel self-developed quality assessment tool. Twenty-five studies met our criteria for inclusion in this systematic review. All studies assessed pain, range of motion and aesthetic deformity, with eight studies also assessing grip strength. The primary indication for surgery was the presence of wrist pain.
Radiologic criteria were used inconsistently and surgical interventions varied. All studies reported post-operative pain reduction in a majority of patients and nearly all studies reported an improved range of motion. Despite nearly years of experience with Madelung deformity, there remains a paucity of information regarding the surgical decision making process due to a lack of uniformity throughout case series.
Generally, various surgical procedures seem to be effective in regards to post-operative pain reduction and increase in range of motion. However, outcomes are reported in a non-uniform manner, prohibiting pooling of studies and comparison of surgical procedures. In Madelungs deformity the Distal Radioulnar joint DRUJ is often involved in the pain pathogenesis especially in moderately to severely affected patients.
We studied the functional outcome one year after Constraint Distal Radioulnar Joint Replacement in patients with moderate to severely affected DRUJ ulnar tilt 37 degrees from 32 to 60 and lunate subsidence 2mm -2 to 5. Aptis in the cohort. Statistics were performed with paired t-test without correction for repeated measurements. To report the usefulness and radiological and clinical outcome of intrafocal pinning for the severely displaced pediatric distal radius fracture.
A retrospective review was performed for the patients treated with Kapandji intrafocal pinning for their distal radius fractures. At the final follow up, radiologic and clinical outcomes were evaluated. This study included 15 pediatric distal radius fractures. The average age was 9 years range years. The inclusion criteria included no physeal involvement, open physis and no cortical contact on initial pre-reduction plain X-ray.
The average location of distal radius fracture was 3. Radial to ulnar insertion was performed in cases with need to restore radial inclination. No ulnar fixation was made in all cases.
